Over six years, the Dark Energy Survey scrutinized 669 million galaxies, shedding light on the mysterious dark energy that accelerates cosmic expansion, while confirming standard cosmology models and unveiling puzzles in matter clustering.

The Dark Energy Survey has released its final report on the forces ripping our universe apart

After analyzing 669 million galaxies, the Dark Energy Survey has released its final report on the forces ripping our universe apart. Dark Matter is invisible, but it has mass. Mass bends light. By measuring the slight distortion of millions of background galaxies, DES created a map of the invisible scaffolding of the universe.

This illustration explores how scientists decode a quasar's echo by analyzing light echoes across various wavelengths. It highlights the composition of quasar dust, revealing that smaller graphite particles dominate near-infrared radiation, while larger silicate particles prevail in mid-infrared radiation, enhancing our understanding of these cosmic phenomena.

Scientists are using the "echo" of light to map the dusty structures surrounding supermassive black holes

Scientists are using the "echo" of light to map the dusty structures surrounding supermassive black holes, revealing a complex mix of graphite and silicate grains. Quasars flicker. When the central black hole swallows matter, it flares brightly in optical light.

A new theory suggests that Io's volcanic landscape and Europa's icy waters were determined at birth by their building blocks. Upcoming missions like NASA's Europa Clipper and ESA's Juice aim to investigate these findings further.

Why is Io a volcanic hellscape while Europa is an icy ocean world?

Why is Io a volcanic hellscape while Europa is an icy ocean world? New research proves they didn't evolve that way—they were built that way from the start. Did Io start out wet like Europa, only to have its water boiled off by volcanic heat and Jupiter's radiation over billions of years?

The NIKA2 survey reveals hidden star formation in the early universe, overcoming dust clouds invisible to Webb and Hubble, suggesting galaxies evolved faster than previously thought.

Astronomers have found a massive cluster of galaxies hiding in plain sight.

Astronomers have found a massive cluster of galaxies hiding in plain sight. Obscured by their own creation—dust—these giants are forming stars at rates that challenge our understanding of the universe. The Paradox: Young stars emit brilliant ultraviolet light. But they form inside dense clouds of dust.

Scientists have revived a 3.2-billion-year-old enzyme, shedding light on Earth’s early history and confirming that ancient enzyme signatures match modern ones. This breakthrough validates nitrogen isotopes as a key biosignature in the quest for life beyond Earth.

Scientists have reverse-engineered evolution to rebuild an ancient enzyme.

Scientists have reverse-engineered evolution to rebuild an ancient enzyme. By putting it inside living bacteria, they are viewing Earth's past—and the future of finding aliens—through a new lens. The Target: Nitrogenase. Without this enzyme turning air into food (ammonia), life as we know it wouldn't exist.

Discovery of a sulfur-bearing molecule, C₆H₅S, 27,000 light-years from Earth bridges interstellar and solar chemistry, suggesting life's building blocks formed before stars.

Astronomers have found a 13-atom chemical ring that bridges the gap between interstellar dust and the origins of life

Deep in the Milky Way, astronomers have found a 13-atom chemical ring that bridges the gap between interstellar dust and the origins of life. Until now, space sulfur was only found in tiny fragments—molecules with fewer than 6 atoms.

A fascinating exploration of the history of a famous comet reveals its connections to medieval observations, its documentation in the Bayeux Tapestry, and the scientific calculations of its orbit by astronomers in the 17th century, urging a reconsideration of its historical naming.

Edmond Halley gets the credit, but a flying monk named Eilmer knew the secret 600 years earlier.

Edmond Halley gets the credit, but a flying monk named Eilmer knew the secret 600 years earlier. "I see you, you bringer of tears..."989 AD: Eilmer, a young monk at Malmesbury Abbey, witnesses a terrifying "hairy star." It coincides with Viking raids and the death of an Archbishop. He never forgets it.

Why do icy comets contain fire-forged crystals?

Why do icy comets contain fire-forged crystals? JWST has found the answer in a violent, pulsating protostar called EC 53. The Paradox: Comets form in the freezing outer reaches of a solar system. Yet, they contain Crystalline Silicates—gems like olivine that require 1000 Kelvin heat to form.

Illustration explores the contrasting polar weather patterns of Jupiter and Saturn, detailing how the softness of interior materials influences vortex formations, with Jupiter exhibiting multiple swirling cyclones and Saturn featuring a single, vast hexagonal vortex.

Why does Saturn have one giant storm while Jupiter has a cluster of them?

Why does Saturn have one giant storm while Jupiter has a cluster of them? New fluid dynamics simulations suggest the answer lies deep underground. Jupiter and Saturn are siblings—similar size, similar gas composition. Yet their weather at the poles couldn't be more different.

Exploring the Hidden Turmoil in Galaxy Cluster Abell 3571: Despite its deceptively calm surface, multiwavelength studies reveal Abell 3571's complex past, marked by disturbances such as gas sloshing from off-axis subcluster passages. X-rays expose asymmetries and internal disruptions, shedding light on the cluster's dynamic history.

New X-ray data reveal that a massive galaxy cluster is still trembling from a cosmic collision that occurred millions of years ago.

It looks calm on the surface. But new X-ray data reveals that this massive galaxy cluster is still trembling from a cosmic collision millions of years ago. The Target: Abell 3571, a titan weighing 910 trillion solar masses. First Impression: To early X-ray telescopes, it looked "relaxed"—a perfect sphere of glowing gas. No signs of trouble.

Comparison of potential biosignatures and mimics in exoplanet exploration highlights the challenge of distinguishing true signs of life, like purple earths and green oceans, from non-biological false positives such as iron oxide and elemental sulfur.

Is Earth the only green planet? NASA's Habitable Worlds Observatory (HWO) aims to find out

Is Earth the only green planet? NASA's Habitable Worlds Observatory (HWO) aims to find out—but it might find purple worlds, green oceans, or red rocks instead.

Earth and Mercury share a cosmic melody: both planets emit similar "birdsong" electromagnetic waves, despite Mercury's weaker magnetic field. These chorus emissions, key in shaping space weather and radiation belts, advance our understanding of universal auroral processes and provide insights for future missions, including upcoming studies by BepiColombo Mio.

Scientists have detected "chirping" plasma waves at Mercury identical to those on Earth

Scientists have detected "chirping" plasma waves at Mercury identical to those on Earth, proving that even tiny magnetospheres can sing. Chorus Emissions: Electromagnetic waves generated by energetic electrons spiraling in a magnetic field. On Earth, they sound like a flock of chirping birds when converted to audio.
